Research on Exploratory Experimental Teaching Based on RLC Series Resonant Circuit Experiment

The RLC series resonance experiment is a basic experimental content in circuit experiments. During the experiment, the error of the resistance voltage during resonance between the measured value and the theoretical value is discovered. The research on the frequency characteristics of inductance AC resistance is induced by exploring reasons for the error. Through the corrparison between experimental methods and instrument measurement methods, theoretical calculations and modeling simulations are carried out with electromagnetic field analysis methods. The exploratory experimental teaching process has improved students’ learning interest, cultivated innovation and research abilities through discovering, raising, analyzing, and solving problems, and it is a beneficial attempt to transform a verification experiment to an exploratory comprehensive experiment.
